“…We did not detect an effect of larval density on the life history traits, t k and T k . However, previous studies have shown the duration of the developmental stage in mosquitoes to be density dependent (Hassell et al, 1989;Delgado, 1998;Aigbodion & Okaka, 2001), with a greater average stage duration detected at higher larval densities (Aigbodion & Okaka, 2001). Moreover, most studies incorporating more than one generation detected this density effect on survival.…”

The larval survival and development times of Aedes caspius (Diptera: Culicidae) were examined in the laboratory. These life history traits were estimated using life tables constructed for two populations, one of which had been subjected to a long-term larvicide control program. Traits were evaluated for eight different population densities. The effects of population, larval stage and larval density were investigated using a general linear model. Density was positively correlated with larval survival but did not affect development time. The fourth instar and pupae had the lowest larval survival rates. First and fourth instar larvae had the longest development times. These traits were not significantly different between the two populations. The effect of larvicide control on these traits is discussed.
